Wordle.

Every day, you're tasked with identifying a new five-letter word in as many as six guesses. After each guess, Wordle tells players whether each letter was right (green), wrong (gray), or right but in the wrong position (yellow), gradually leading them closer to the solution. (There is also a color-blind mode that swaps the yellows for blues and greens for oranges.) The ostensible goal is to find the word in as few turns as possible.
